LUBRICATOR.

`SPECIJE'IJATION forming part of Letters Patent No. 298,813, dated May 20, 1884r. Application filed February 23, 1884. (No model.)

To all w/Lom it may 0070067771:

Be it known that I, LUTHER B. BAILEY, of London, inthe county of Middlesex and Province of Ontario, Canada, have invented new and useful Improvements in Lubricators; and I hereby deolare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention. relates to certain new and useful improvements in lubricators, adapted to supply tallow, grease, oil, or their equivalents in a steady, continuous, and even flow, and in any quantity required to the part requiring such lubrication.

The invention consists in a new and novel arrangement of chambers and passa-ges leading from the lubricant-reservoir into the steampipe; also, in combination a valve-spindle provided with au elongated tapered Valve end, the smaller portion of which governs the lnbricant-outlet, and the larger portion of which governs the steam-inlet, so that when the Valvespindle is operated to enlarge or reduce the steam-inlet and lubricant-Outlet it retains the same relative proportion of the areas of the two openings; also, in the peculiar construction and combination of parts, as more fully hereinafter described.

Figure 1 is a side elevation, partially in section, showing the position of the Valve-spin- (lle when the steam-inlet and lubricant-Outlet are closed. Fig. 2 is a sectional elevation on the line x x of Fig. l with my improved gageglass attachment in position. Fig. 3 is a sectional View of the ehambers, Valve, spindle, and passages when a gage-glass is employed, showing the position of the valve-spindle when the steam-inlet and lubricant-outlets are partially open. Fig. 4: is a sectional attachment to the lubricator, showing the feed of the lubricant after it leaves the lubricator.

In the accompanying drawings, which form a part of this specification, A represents a steam-pipe, to which this lubrieator is secured in any of the known ways.

B is a reservoir to contain the lubricant, and near the lower end of this chamber or reservoir are chambers G G', passages F, I, and H H', and Valve-spindle D, provided with an elongated tapered end, N. The steam-inlet G is eonstructed larger than the lubricantoutlet G', and in sufficiently larger proportion that the steam will always enter the larger opening or steam-inlet, O, and pass out with the lubricant through thesmaller opening or lubricant-Outlet, O. The smaller portion of the tapered end N of the valve-spindle D governs the lu bricant-outlet O, and the larger portion of the tapered end N of this Valve-spindle D governs the steam-inlet O, so that when only one Valve-spindle, D, is used and operated to enlarge or reduce these openings C C', the same relative proportion of the areas of the two openings must always be retained, and by retaining the same relative proportion of the areas of the steam-inlet O and lubricant-outlet U the lubricant is fed in a steady, continuous, and even flow to the steam-pipe, and by enlarging or reducing these openings O G' by the Valve-spindle D the lubricant is fed to the steam-pipe in any quantity required.

E is the eap of the lubricator, through which the lubricant is introdueed into the reservoir B.

F is a passage leading from the reservoir B, and oonnecting with the chambers G G' by means of the passages H H'.

I is a passage connecting with the chamber G by the steam-inlet O, and with Chamber G' by the lubricant-Outlet 0/. In filling the reservoir B with the lubricantused the chambers G Gl and passages F and H H/ are also filled.

In practice the steam from the steam-pipe A passes through the passage I, and on operating the spindleD to open the steam-inlet O and lubricant-Outlet O' the steam enters the opening which has the largest area or steaminlet O, and passes out into the Chamber G and through passage H into the passage F, and intermingles with the lubricant and disintegrates the same, and then this disintegrated lubricant is forced by the steam through the passage H/ and Chamber G' out at the lubricant-Outlet O' into the passage I, and passes thence to the steam-pipe A, and is carried therein by the contained steam to the throttle- Valve or other part of the engine requiring lubricaton; and the areas of the openings of the steam-inlet O and lubricant-Outlet O' being` regulated by the elongated tapered end of the Valve-spindle D as the spindle is operated to allow the lubricantto feed, this lubri- IOO - required quantity.

When the valve-spindles D DI are adjusted with the steam-inlet O and Outlet R open, the sediment, if any, collected in the passagcs or chambers is blown out through the Outlet R and out of the lubricator through the passage L into the lower mctallic portion of the glass gage. X'Vhen the Outlet R is open only and the steam-inlet O is closed, the steam is allowed to escape from the reservoir B before refilling it with the lubricant, and the water of condensation passes off with the steam.

In Fig. 4 there is shown an attachment for showing the feed of the lubricant after the' same leaves the lubricator. In this figure A/ is the body of the attachrnent, with a hole, f, bored through the side for the purpose of allowing the gage-glass O' (which is inserted vertically therein) to be seen. This gageglass is packed steam-tight by the rubber gaskets a and Z), one being at either end. The one at the upper end is compressed by a thimble, M, and the lower one by the coupling-nut S. The lubricator is screwed on at its discharge end to the upper end 'of the attachment, the lower end of which is attached to the steam-pipe, or wherever desired.

The steam-inlet O and Oil-Outlet C' need not neeessarily'be in the above positions, but may be separated, and may be operated by separate valves so long as the steam-inlet O is or can be made larger by the operation of the valve than the Oil-Outlet 0', and so long as these` openings are in any way connected wlth the lubricant-reservoir B, and between it and the parts to be lubricated, with which they communicate. This modification I consider to be within the scope of my invention.

,What I claim as my invention is- 1. In a lubricator, a valve-spindle with an elongated tapered Valve end, the upper or larger portion (of which regulates the steaminlet, and the smaller portion the lubricant- Outlet, in combination with valve-seats of different areas, substantially as 'and for the purposes described.

2. In a lubricator, the combination of the Oil-reservoir thereof, having a passage or passages leading therefrom communicating with the parts to be lubricated, two openings Or valve-seats of different areas, the larger being for the admission of steam,.and the smaller being the oil-Outlet, and a single tapered valve controlling such openings, substantially as and for the purposes specified.

3. In a lubricator, a Valve-spindle, D, provided with an elongated tapered Valve end, N, in combination with the steam-inlet O and lubricant-outlet O, such inlet and Outlet being of different areas, and arranged with relation to the spindle, substantially as and for the lpurposes described.

4. In a lubricator, the combination, with the reservoir thereof, of the chambers G G',passages F I and H H', steam-inlet O, lubricant- Outlet O', and valve-spindle D, provided with an elongated tapered Valve end, N, the parts being arranged, constructed, and Operating substantially as and for the purposes set forth.

5. In a lubricator, the combination, with the reservoir thereof, of the chambers G G',

'passages F I and H H', steam-inlet O, lubricant-Outlet O', valve-spindle D, provided with an elongated tapered valve end, N, passage K, and Outlet P, the parts being constructed, combined, and Operating substantially as and for the purposes set forth.

6. In combination with a lubricator constructed substantially as described, a glassgage, O, provided with passages H communicating with the parts to be lubricated, Outlet It, valve-spindle D', and passage L, substantially as shown, and for the purposes specified.
